The direction of eye movement in Pleuronectiformes is species-specific. In farmed flounder, deviations in eye direction can reduce marketability. Therefore, we explored the effects of genetic and environmental factors on the direction of eye movements in the starry flounder Platichthys stellatus to address this economic challenge. Four pairs of female and male starry flounder broodstock, with eyes positioned to the right or left, were used in a mating experiment. The experimental groups were established with breeding seawater temperatures set at 10, 14, and 18°C for the water temperature experiment. Whole-body samples of juveniles were collected to analyze the expression of genes related to eye movement and direction. The mating experiment results showed no significant differences in abnormal eye movement. In the water temperature experiment, the rate of abnormal eye movement was significantly higher at 32.19±1.33% in the 18°C group than in the 10 and 14°C groups. Genetic analysis of eye movement related to water temperature revealed that the expression of eye migration genes was significantly higher at 10°C. Moreover, no significant differences were observed in mating experiments. In conclusion, water temperature and not mating affected the eye movement of starry flounder.
